Are covered bonds different from securitization bonds? A comparative analysis of credit spreads

This study compares credit spreads and pricing determinants of securitization vis-à-vis covered bonds. Our analysis reveals that although ratings are the most important pricing determinant for asset-backed securities (ABS) and mortgage-backed securities (MBS) investors place relatively more importance on contractual, macroeconomic and banks' characteristics rather than ratings in pricing covered bonds. We find evidence of a mispricing effect in structured finance markets: ABS and MBS have higher credit spreads than similarly rated public-covered bonds and mortgage-covered bonds and security prices reflect information beyond credit ratings. We find no evidence of borrowing costs affecting banks' choice between securitization and covered bonds.     

Factors affecting the yields of emerging market issuers: Evidence from the Asia-Pacific region

We investigate the yield spread between the sovereign bonds issued in international markets by major Asia-Pacific issuers (China, Korea, Malaysia, Philippines and Thailand) and matched with near maturity benchmark U.S. Treasury bonds (2, 5, 10 year maturities) to determine the extent that various factors affect changes in credit spreads. The results suggest that the credit spreads of these sovereign bonds tend to be negatively related to changes in interest rates on U.S. benchmark bonds and positively related to changes in the slope of the yield curve. The asset and exchange rate variables were only significant for spreads on Philippine bonds where it was negatively related to changes in the local stock market index, and positively to changes in the exchange rate. The complex dynamics of these processes highlight concerns for portfolio mangers when constructing portfolios of sovereign Asian bonds by aggregating bonds of different credit ratings.     

THE EFFECT OF MONETARY POLICY ON CREDIT SPREADS

We analyze the effect of monetary policy on yield spreads between corporate bonds with different credit ratings over the business cycle. We use futures contracts to distinguish between expected and unexpected changes in the Fed funds target rate and several indicators to distinguish between different phases of the business cycle. In line with the predictions of imperfect capital market theories, we find that yields on corporate bonds with low credit ratings widen (narrow) with respect to those with high credit ratings following an unexpected increase (decrease) in the Fed funds target rate during recession periods. Several tests suggest that our results are robust to outliers, potential endogeneity problems, empirical specification, control variables, countercyclical risk premium in futures, and alternative definitions of credit spreads and economic conditions.     

News spillovers in the sovereign debt market

We study the effect of a sovereign credit rating change of one country on the sovereign credit spreads of other countries from 1991 to 2000. We find evidence of spillover effects; that is, a ratings change in one country has a significant effect on sovereign credit spreads of other countries. This effect is asymmetric: positive ratings events abroad have no discernable impact on sovereign spreads, whereas negative ratings events are associated with an increase in spreads. On average, a one-notch downgrade of a sovereign bond is associated with a 12 basis point increase in spreads of sovereign bonds of other countries. The magnitude of the spillover effect following a negative ratings change is amplified by recent ratings changes in other countries. We distinguish between common information and differential components of spillovers. While common information spillovers imply that sovereign spreads move in tandem, differential spillovers are expected to result in opposite effects of ratings events across countries. Despite the predominance of common information spillovers, we also find evidence of differential spillovers among countries with highly negatively correlated capital flows or trade flows vis-á-vis the United States. That is, spreads in these countries generally fall in response to a downgrade of a country with highly negatively correlated capital or trade flows. Variables proxying for cultural or institutional linkages (e.g., common language, formal trade blocs, common law legal systems), physical proximity, and rule of law traditions across countries do not seem to affect estimated spillover effects.     

Longitudinal accounting comparability and bond credit spreads: Evidence from China

This paper proposes a procedure to measure firms’ longitudinal accounting comparability and investigates whether it affects bond risk premiums. The results provide robust evidence that bonds of firms with more longitudinally comparable accounting information have lower credit spreads. This effect is stronger when the firms’ financial performance is poor and for bonds with speculative credit ratings. Results also reveal that firms with less longitudinally comparable accounting information are more informationally asymmetric and do have a higher expected default probability. Finally, the effects of the longitudinal and the cross-sectional comparability in reducing bond credit spreads are incremental to each other.     

Recognition versus disclosure of finance leases: Evidence from Japan

This study examines whether credit market participants—bond investors and credit rating agencies—treat recognized and disclosed finance leases differently when assessing firms’ credit risk in Japan. I use firms’ credit risk, measured by bond spreads and credit ratings, to investigate the relations between recognized versus disclosed finance lease obligations and firms’ credit risk following the adoption of Statement No. 13, Accounting Standard for Lease Transactions. For a sample of firms issuing new bonds, I find that, unlike recognized finance leases, disclosed finance leases are not associated with bond spreads. Moreover, the associations between recognized versus disclosed finance leases and bond spreads are substantially different. Conversely, recognized and disclosed finance leases are associated with credit ratings and are processed similarly when credit ratings are determined. Taken together, my results suggest that the sophistication of capital market participants influences their credit risk assessments of recognized versus disclosed finance leases.     

Information uncertainty,information asymmetry and corporate bond yield spreads

This study examines the effects of information uncertainty and information asymmetry on corporate bond yield spreads using American data from 2001 to 2006. Empirical results of this study show that investors charge a significant risk premium for both information uncertainty and information asymmetry when controlling for variables well known in the literature. The results are robust even when controlling for credit ratings. Finally, information uncertainty and asymmetry help structural-form credit models explain the yield spreads of bonds with short maturities.     

CDOs and the financial crisis: Credit ratings and fair premia

We study risk and return characteristics of CDOs using the market standard models. We find that fair spreads on CDO tranches are much higher than fair spreads on similarly-rated corporate bonds. Our results imply that credit ratings are not sufficient for pricing, which is surprising given their central role in structured finance markets. This illustrates limitations of the rating methodologies that are solely based on real-world default probabilities or expected losses and do not capture risk premia. We also demonstrate that CDO tranches have large exposure to systematic risk and thus their ratings and prices are likely to decline substantially when credit conditions deteriorate.     

CREDIT SPREADS AND THE ZERO‐COUPON TREASURY SPOT CURVE

We examine the relation between credit spreads on industrial bonds and the underlying Treasury term structure. We use zero‐coupon spot rates to eliminate the coupon bias and to allow for a consistent study both within and across the different credit ratings. Our results indicate that the level and slope of the Treasury term structure are negatively correlated with changes in the credit spread on investment‐grade corporate bonds. We also find that the relation between credit spreads and the Treasury term structure is relatively stable through time. This is good news for value‐at‐risk calculations, as this suggests that the correlations among assets of different credit classes are stable; therefore use of historic correlations to model spread relations can be valid.     

What causes mean reversion in corporate bond index spreads? The impact of survival

Previous studies document that the spread between the yield on commonly used corporate bond indexes (e.g., Moody’s Baa index) and a comparable maturity treasury bond exhibits mean reversion. An analytical model shows that a part of the observed negative relationship between changes in the spread and the level of spreads is a natural consequence of ratings based classification of bonds included in the index and the related effects of survival. Using data on individual corporate bonds over the period January 1985 to December 1996, I corroborate the analysis and illustrate the effects of survival. The result has several implications for parametric specifications of spread dynamics in the pricing of contingent claims, for the application of spreads in tests of asset pricing models (such as the conditional version of the CAPM) and for the use of spreads in business cycle forecasts.     

THE DYNAMICS OF BOND YIELD SPREADS AROUND RATING REVISION DATES

We examine the effect of rating revisions on sterling Eurobond yields using a panel model with conditional heteroskedasticity that controls for event‐induced changes in the variance of spreads. Positive rating revisions are fully anticipated by the time the upgrade occurs. Negative revisions are only partially anticipated, and spreads on downgraded bonds rise for some time after the downgrade has been announced. This asymmetry is not apparent in a conventional event study model. All ratings announcements are accompanied by a temporary fall in yield volatility. We attribute this to the resolution of uncertainty about the true rating of the bond.     

A Markov model for the term structure of credit risk spreads

This article provides a Markov model for the term structureof credit risk spreads. The model is based on Jarrow and Turnbull(1995), with the bankruptcy process following a discrete statespace Markov chain in credit ratings. The parameters of thisprocess are easily estimated using observable data. This modelis useful for pricing and hedging corporate debt with imbeddedoptions, for pricing and hedging OTC derivatives with counterpartyrisk, for pricing and hedging (foreign) government bonds subjectto default risk (e.g., municipal bonds), for pricing and hedgingcredit derivatives, and for risk management.     

Do investors care about credit ratings? An analysis through the cycle

We investigate how the credit cycle affects the link between bond spreads and credit ratings. Using a simple model of the credit assessment process, we show that when the debt market is more opaque, the information content of ratings deteriorates, creating an incentive for investors to increase the amount spent on private information. We test this hypothesis empirically. Results show that when market opaqueness (proxied by the spread between Aaa- and Baa-rated bonds) increases, the explanatory power of ratings and other control variables deteriorates as investors increasingly price in non-public information.     

Unsolicited Versus Solicited: Credit Ratings and Bond Yields

This paper is the first attempt to analyze Standard & Poor’s unsolicited and solicited ratings by using bond-yield data in Japan. Our findings show that there are differences in firm characteristics between firms seeking solicited ratings and those that receive unsolicited ratings. Firms with solicited ratings have less information asymmetry and are more likely to be owned by foreign investors, generate more revenue from exports, be cross-listed in the US, and have higher firm quality. But, firms with unsolicited ratings pay higher costs for debt, and their bond prices react more strongly to credit-rating changes. Yield spreads for new bonds with unsolicited ratings are higher than those with solicited ratings, because unsolicited ratings have higher information asymmetry, and investors therefore demand higher yields. We find that bond-price reactions to the announcements of unsolicited rating downgrades (upgrades) are negative (positive) and significant, while bond prices do not react significantly to solicited rating downgrades or upgrades.     

Do Bond Covenants Affect Borrowing Costs?

High yield bond investors spend a great deal of time studying covenants. They even hire specialized consultants to help them interpret the dense language of indentures. But for all that, does a company's decision to offer strong rather than weak covenants—or to offer covenants at all—have a measurable impact on its borrowing costs? There is surprisingly little evidence that variation in credit risk premiums reflects the presence or absence of covenants. Taking advantage of a newly available kind of data—Moody's Investors Service's Covenant Quality (CQ) ratings, which were initiated in 2011—the authors studied each newly issued U.S. high yield bond beginning in 2011 using Moody's CQ ratings, where a rating of “1” represents the strongest covenant rating and “5” the weakest. The authors hypothesize that if investors are willing to pay for covenant protection, bonds with weak CQ scores should have spreads that are higher, on average, than the medians of the bonds in their rating group. What they found, however, was that even bonds rated CQ5, indicating negligible protection, had spreads that were only 9.54 basis points higher than the median of companies with the same credit rating. The authors also found, contrary to their initial supposition, that higher yields were associated with stronger covenants, suggesting that investors demand more protection on issues they view as having greater credit risk than other equivalently rated issues.     

Insider employee stock option trading and stock prices

The question of which factors determine corporate bonds pricing is investigated by analysing the spreads of eurobonds issued by major G-10 companies during the 1991–2001 period. Three main results emerge from the analysis. First, bond ratings appear as the most important determinant of yield spreads, with investors’ reliance on rating agencies judgments increasing over time. Second, the primary market efficiency and the expected secondary market liquidity are not relevant explanatory factors of spreads cross-sectional variability. Finally, rating agencies adopt a different, ‘through the cycle’, evaluation criteria of default risk with respect to the forward looking one adopted by bond investors.     

CSR in the bond market: Pricing stakeholders and the moderating role of the institutional context

This study examines the impact of corporate social performance (CSP) on the spreads and credit ratings of corporate bonds on a global scale. The relationship is examined within the national legal and institutional environment and with regard to specific stakeholder practices. We construct and use a unique longitudinal, international dataset with a total of 5280 bond issues dating from 2003 to 2018 and spanning 40 countries worldwide.We provide evidence that more responsible firms benefit from lower bond spreads and improved bond ratings, while a higher degree of CSR-related controversies penalizes firms on both dimensions. Various, but not all, stakeholder relationships appear to generate a significant impact on spreads and bond ratings, with shareholders remaining crucial in both civil and common law countries, opposite to literature findings so far. Corporate governance is corroborated as a primary concern also in the debt market for common law economies, while societal stakeholders assume significance for civil law systems. Finally, findings highlight that stronger regulation and government involvement do not further promote the role of CSP in the debt market. On the other hand, free public criticism and media scrutiny generate a more pronounced effect of CSP on bond pricing providing support for the rewards associated with voluntary and proactive CSR.     

Does sovereign risk matter? New evidence from eurozone corporate bond ratings and zero-volatility spreads

In this paper, we empirically examine if sovereign risk matters for corporate bonds in developed economies. Using a unique panel data sample of 897 corporate bonds from eleven countries within the Economic and Monetary Union (EMU), we investigate sovereign and corporate ratings as well as zero-volatility spreads (z-spreads). In the time period from March 2006 to June 2012, we find sovereign risk to be a significant driver of corporate risk. The effect is stronger for companies with domestic revenue structure, for companies that are (partly) owned by the government, and companies active in the utility and transportation sector. Interestingly, the impact of sovereign risk on corporate risk during the acute European sovereign debt crisis period decreases if ratings are examined, but increases if z-spreads are utilized. Rating agencies seem to take a more differentiated view on individual company risk during the sovereign debt crisis, while institutional investors might want to reduce their exposure to a country in financial distress as a whole, regardless of whether sovereign or corporate bonds are held.     

News spillovers from the Greek debt crisis: Impact on the Eurozone financial sector

We examine the impact of changes in Greek sovereign yield spreads on abnormal returns of financial sector stocks for a sample of Eurozone countries, during the Greek debt crisis. We find that increases in yield spreads are associated with negative abnormal returns on financial stocks in the Portugal, Spain and Netherlands. These abnormal returns are driven in part by ratings downgrades and other unfavorable news announcements about Greece. We isolate the effects of known transmission channels–impairment of financial firms’ asset base due to cross-holdings of Greek bonds, from increases in domestic interest rates and higher funding costs. Our analysis indicates that news events lead to spillovers in excess of what can be explained by these channels of transmission.     

Locational effects and the cost of corporate bonds: the role of information

The public yield spreads of bonds vary widely between Chinese provinces/municipalities, with the average for the highest province double that of the lowest one. Although we find that these patterns are mainly attributable to economic and legal conditions, locational effects like geographic distance and public firm credit ratings also appear to be contributory. We show that these effects are induced by different regional informational environments and are robust to controlling for potential endogenous location choices.
